e-harmony this site does a psychological assessment initially and such a disorder would probably be identified, as well as one would self-identify, hopefully. Getting together with others for dating and friendship is not something that someone with an anti-social personality disorder would usually do in good faith, so this is an interesting question. On-line friendship leading to dating takes a lot of patience and tolerance and a good amount of social skill. Not a strong point for P.D. folk. However, worth a try as long as you are upfront.

Hi. Avoidant-Borderline here, so I don't know how this will apply to you. I think eharmony is total absolute garbage unless you're a boring drone with the same personality every moment of every day. I guess it could work for the cookie-cutter sheep out there, but the loners/antisocialites I know tend to have non-stop brain activity scattered all over the map day by day or minute by minute. I have undergone eharmony profile creation in the past and even though I'm brutally honest in answering the phyche questions, at another time of the week I would have answered very differently. Trying to match a profile based on their criteria is as silly as deciding where to shop for a green shirt by profiling the number of green cars in the parking lot. If you fall in to that "scattered" category, hopefully there are a few core aspects of your life that are fairly static...intense love of music in one particular genere, certain fetish, type of art, unusual hobby, etc. If this is the case, you can search for groups or dating/social sites in those specific areas. That's been the only way I've had any degree of success meeting like minded antinormies.

Yeah, this one! Take your pick...

Wouldn't that be socially counterintuitive?

You could look at ascotworld matchmakers.
